His use of the b-word in the tweet is quoting Spears' 2007 song, "Gimme More."

Not everyone believes he wasn't talking about Spears, however. Wrote one Twitter user, "it seems that u still have feelings for Britney or else u wont be bringing her up every time. BOW DOWN TO THE QUEEN."

Timberlake wed actress Jessica Biel in October 2012. Spears was engaged to Jason Trawick, but they announced in January that the wedding was off.
